At present, Sub-Himalayan West Bengal and Sikkim along with Gangetic West Bengal is rain deficit by 33% and 55%, respectively. In the past 24 hours, heavy to very heavy rains have been seen over the parts of Sub-Himalayan West Bengal and Sikkim. Places like Siliguri which recorded 52 mm of rains, Jalpaiguri 42 mm with Darjeeling 2 mm of rains. Whereas, the weather over Gangetic West Bengal remained dry.
Now, the experts have to say that Sub-Himalayan West Bengal and Sikkim will continue to witness good rain and thundershowers for the next two to three days. On the contrary, rains would skip Gangetic West Bengal for the next 24 to 48 hours. Thereafter, around June 28 or June 29, we expect rainfall activity in Gangetic West Bengal inclusive of Kolkata and adjoining areas. These rains will be light to moderate in nature in wake of a Low-Pressure area which is likely to develop around Northwest Bay of Bengal around June 30. Further, this system would act as a catalyst and rain activities will pick up pace in many parts of West Bengal. However, the intensity will be more over the state of Odisha.
Therefore, light to moderate rain and thundershowers will be a sight in Gangetic West Bengal between June 30 to July 1. While on July 2 we can expect moderate rains with one or two heavy spells over Gangetic West Bengal as the Low-Pressure Area will start travelling inland towards Odisha. Thus, a significant increase in rains will be seen during this time. Thus, we can conclude by saying that rains of good intensity will be a sight on Gangetic West Bengal in the first week of July.
